Sil 3114 and two disk
Hi, I have a Gygabite MotherBoard with Sil3114 Raid Chipset and 2 HD. Into the bios of Sil 3114 I have set one Raid0 so when I boot the PC (before the boot manager menu) I see the text: "Sil0 138GB". Ok, it is correct. Now I want to install Suse 9.3 Pro, I boot from DVD and I see 2 HDx73GB and not HD 1x138GB. Why ? This is correct ? Tnx in advance for all and sorry for my bad english. M.

Just a quick guess: is the RAID chipset one of the "famous" Software-RAIDs (where actual RAID processing is done by a operating system driver software on your CPU instead on the chip)? If so, you will probably have no Linux 2.6.x support for this chip and need to do a linux RAID setup using md,lvm and the like. -- Volkmar Glauche - Department of Neurology volkmar.glauche@uniklinik-freiburg.de Universitaetsklinikum Freiburg Phone 49(0)761-270-5331 Breisacher Str. 64 Fax 49(0)761-270-5310 79106 Freiburg

Hello, I'm trying to use Sil3114 Raid too. Into the Bios of Sil 3114 I have set one Raid1 with 2 HDx73GB. Yast shows me than one of them (73GB) and I createt one partition "/work" for my data with Yast. (I don't know if I done right.) It seems running OK. But I'm looking for a manage tool, too see if the raid is working OK. Something how the :-) Adaptec-StorageManager for SCSI. Your problem is: AFAIK booting or install "/" (root) to raid0 is impossible. If you really want raid "/" then: (But its not good. Copy it to a spare part, for rescue booting; is better) First make a "/boot" part and a raid1 "/" and then try install to "/" Raid0 is a good choice for "/var" ; "/var/tmp" ; "/tmp" A good start is here: http://www.nyx.net/~sgjoen/disk.html http://www.nyx.net/~sgjoen/disk-4.html -- Ciao Marco, registered GNU/Linux-User 313353
I think you'd be better off if you: - turn off all RAID options in BIOS and set the Sil3114 to be ATA-only (or the equivalent) - in fact, I would just plug your drives into the normal IDE controller(s) on the motherboard and ignore the Sil controller (unless you need the extra connectors) - use Linux Software RAID (easy to create RAID volumes during SUSE partition setup in Yast) Doesn't it seem like a waste to have a "fancy" RAID-enabled motherboard and then not use the RAID features? Yes, but these features are not much more than marketing hype. As I understand it, the Linux software RAID will probably be faster as well! On Friday 13 May 2005 10:24 am, zio budda wrote:

[BEGIN MILD RANT] Though you are right, that the cheap raid on motherboards is "fake" - for Windows users it seems really great and works pretty close to real hardware RAID. You simply: - You use the bios utility to create your RAID volume, and - Install the correct RAID driver. You end up with a nice, simple RAID1 or RAID 0 (who values their data that little, I do not know) setup. Yes, I know that Linux software raid can be faster, but no matter how you slice it its hard to get a a true "mirrored" disk drive setup using RAID. With a lot of configuration you can mirror ALMOST all of your partitions. Some has said they can even figure out how to mirror the boot and "/" partitions - but it's a lot of work. I've also ended up with unbootable MD RAID partitions a number of times - can they be fixed, yes, but it's a pain. I've been fighting this for over a year and a half with Highpoint PATA controllers. Put plainly, the Linux support sux compared to the Windows support. I should not be surprised - and am not about to switch all of my computers to Windows (I run one XP workstation, though). But its still irritating. I do hear that support for some of the other brands of controllers may be better. [END MILD RANT] Anybody have any different experience? Thanks - Richard

Really? Insert SuSE DVD - go into partitioner, set / for RAIDN (N=0..5), set any other partitions for RAIDN, install Linux system as per normal, reboot, finished. Has been like that for years, though up to about 2 years ago yast only allowed to set up one raid volume during install beacsue of some silly bug. You made that the root filesystem then and changed the others later.

Highpoint is rubbish, just treat them as an IDE controller and you won't have any more problems with stupid/limited/propritary hardware.
Anybody have any different experience?
Yes. You can't blame your choice of $DISTRO on Linux raid support. Volker -- Volker Kuhlmann is possibly list0570 with the domain in header http://volker.dnsalias.net/ Please do not CC list postings to me.
